Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed April 17,1905. $erial No. 256,068.

To all whom, it may concern:

Be it known that I, EDWIN JAMES STELJEs, electrical engineer, a subjectof the King of Great Britain and Ireland, residing at Mount View, MountPleasant Road, South Tottenham, London, in the county of Middlesex, haveinvented a new and useful Improvement in and Relating to Type-PrintingTelegraphs, of which the following is a specification.

This invention relates to type-printing telegraphs, and consists in thearrangement of a WVheatstone transmitter with an added typewriter tofacilitate its use in transmission.

Figure 1 is afront elevation of a transmitter with a known recorder uponthe same stand. Fig. 2 is a side elevation of the same. Fig. 2 is a planof the .Wheatstone transmitter on the line Z T in Fig. 3.. Fig. 2 is anelevation of the spindle and frictional accessories thereto. Fig. 3 is aside elevation of the arrangement of type-writing devices operating aWheatstone transmitter. Fig. 4 is a plan of the Wheatstone transmitter,taken along the line X Yin Fig. 3. Fig. 5 is a side elevation of asynchronizing-key and the gear it operates in a Wheatstone transmitter.Fig. 6 is a plan of the same. Fig. 7 is a side elevation of the same.

In Figs. 1 and 2 I show the general arrangement of a transmitter mfitted with a type-Writer M and a single recording instrument A of thetype in which a type-Wheel is included and in which the printing iseffected by the cessation of the current in the line. Underneath thetransmitter is fitted a motor N, operating an electro generator n. Thecenter of this motor-shaft is fitted with a worm n, which operates by aworm-wheel a horizontal shaft n for driving by the pulley n and a rubberband thereon the shaft and pulley F of the recorder. It also drives avertical shaft n to the transmitter by another Wormwheel, which operatesthe transmitter, as described below.

In order to explain the general action of a the stop device m thrustsback the pawl B out of the teeth a. This stop device m is moreparticularly described hereinafter. The wheel A thus goes on, togetherwith the shaft it, while the pawl-lever C, tending to carry with it byfrictional contact the contact making and breaking tail-lever C, stopsat rest according to the position of the interpolated stop m WVhile thetransmitter is traveling with the pawl B in contact with the teeth a ofthe Wheel A, the tail-lever C makes a contact ,with the fixed stop orcontact D, being in frictional contact with this lever C by the springpressing it against the upper broad surface of C. This completes thecircuit between the generator at to a distant receiver. As the pawl Band the arm C is arrested by an interpolated stop device the arm C isthus stopped, ceasing to produce a frictional entrainment upon the leverC. The tail-lever C is thus pulled from the stop or contact D by thespring e to the stop or contact D. This breaks the current transmitted,the number of alternate impulses in the said current being proportionalto the distance traveled by the arm C from O to the interpolated stop,which is thus caused to operate the receiver type-wheel to make thenecessary movements from its position of O to the same indicated letteras corresponds to the interpolated stop device m The arrangement of thetype-writing device with the Wheatsone transmitter is shown in Figs. 3and 4. m are a series of bent levers, each representing separate letterson the Wheatstone transmitter. When one of these levers m is rockedinward, so that the lower part comes in toward the center, it meets thespring I), as described in relation to Figs. 2 or 2 where it forms astop, pressing in the chain 19 of the transmitter and ar resting themovement of the revolving arm C, causing by the movement of the lever Cto the stop D a stoppage of alternating current through the transmitter.The levers m are each connected up by a rod m to the axially-movingshafts m which are arranged three above one another and are connecteddirectly to the keys m, each marked with a separate letter.

In Figs. 5, 6, and 7 is shown a special clearance-key P. This operateson a rock-shaft p, which by a rocking lever p operates a bell-crank 19This pulls a sliding bar 19 which by a pulley lying Within thetransmitter-chain p pulls out the slack of this chain,

so as to pull out the stopping device, which is left inserted by theaction of the transmitter. As all the stops m are thus pulled out, oneof which always remains in by the action of the transmitter, thisoperation clears the path of the traveling arm 0, enabling it to make asmany complete turns as are necessary. Upon any known recorder isinvariably fixed a special device for bringing the type-wheel of such arecorder into accord with the transmitter, it being requisite that thetransmitter should make a series of turnssay three completerevolutions-for the purpose. The action of this clearance-key P enablesthe transmitter to be continuously revolved until the necessary accordis made between the type-wheel of the recorder and the trans mitter.

This motor may be supplied with a commutator reversing the direction ofa linecurrent taken from a battery source by which the current isalternatively reversed for the main-line circuit.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. In combination in a type-writing transmitter a key to a knownWheatstone transmitter, pierced with a hole at its end, a connecting-rodengaging the hole, a rock-shaft, a crank upon said rock-shaft operatingthe said connecting-rod and another crank upon the said rock-shaft and avertical rod having a button thereon and actuating the transmitter-crank.

2. In combination in a type-writing transmitter, including a rotary arm,means employed to make the path of the revolving arm free forsynchronization consisting of a special finger-key, a rock-shaft, meansfrom the said finger-key to operate said rock-shaft and a hinged leveroperated from said rockshaft, a bell-crank operated by said lever, alever carrying a roller within the transmitterchain operated by the saidbell-crank to draw up the said chain, so that the latter may be extendedby the said apparatus to free the path of the revolving arm of thetransmitter to permit synchronization.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWIN JAMES STELJES.
